Mayor Bloomberg yesterday called on developer Larry Silverstein to put the brakes on rebuilding 7 World Trade Center until there’s an overall plan for the entire Ground Zero site.

“I don’t know that you can go any faster than what you’re doing right now,” Bloomberg told reporters at his daily press conference.

“So I certainly would recommend stalling a little while longer. I think over the summer you’ll start to see people be able to sit down and look at a more comprehensive plan,” he added.

“You should not go build any one building without a plan.”

Bloomberg’s comments – his strongest yet about what gets built at the former trade center site and when – came a day before a planned meeting with some of the victims’ relatives groups, who’ve said they’re upset that the rebuilding pace may be moving too quickly.

Silverstein, who built 7 WTC and held the lease on the Twin Towers, has said he wants to break ground as early as June on a new 7 WTC, which stood across the street from the Twin Towers.
